For the Rolls-Royce Wraith (RR5) and Ghost (RR4), the part number 63127322036 (or 63.12-7322036) refers to the Front Right (Passenger Side) Xenon/Adaptive Headlight Assembly.

This specific headlight was the standard for the Series I and early Series II transition models (typically 2010–2018). By 2026, these are frequently sourced as high-quality used units or remanufactured assemblies.

1. Component Details & Part Number

• Part Number (Right): 63127322036

• Matching Left (Driver) Part Number: 63127322035 (typically)

• Application:

  • Ghost (RR4): 2010–2018

  • Wraith (RR5): 2013–2018

• Technology: Bi-Xenon with Adaptive Function (swivels with steering) and integrated LED Daytime Running Lights (DRLs).

• Adaptive Front-lighting System (AFS): This unit is “active,” meaning it adjusts the beam pattern based on speed and steering angle to illuminate corners.

• The “Yellow DRL” Issue: A common fault for this generation in 2026 is the LED light guide turning yellow or dimming. If you are buying a used unit, specifically ask for a photo of the Daytime Running Lights active to ensure they are crisp white.

• Lens Material: High-impact polycarbonate with a UV-resistant coating. If your current headlight is just “cloudy,” you can often replace just the lens cover for approx. $150 rather than the whole $2,000 assembly.

3. Installation & “Bare  vs. “Complete”

When purchasing this part number, clarify if it is a “Complete” or “Bare” unit:

• Bare Unit: Includes the housing and lens only. You must transfer your old Xenon Ballast, LED Modules, and AFL Control Unit.

• Complete Unit: Includes all modules (Part No. 63117316336 for the control module). This is “Plug-and-Play” but significantly more expensive.

• Coding: Even with a complete unit, you may need to perform a “Headlight Commissioning” via a diagnostic tool (ISTA) so the car recognizes the new stepper motors for the adaptive steering function.

4. Verification Checklist for 2026

1. Check for “Pitting”: These low-slung headlights are prone to stone chips. Ensure used units haven’t been heavily “sandblasted” by road debris.

2. Mounting Tabs: The plastic tabs are fragile. Verify that all three main mounting points are intact; repaired tabs (plastic welded) can cause the headlight to vibrate or sit unevenly against the fender.

3. US vs. EU Spec: Ensure you are buying the correct version for your region. US Spec units (SAE) have an amber side reflector, while European Spec (ECE) units are clear.
